A switch is arrange between that resistance of the weatherproof socket and the electromagnetic switch; the fuse and the electromagnetic switch are connected with a pow line; the power line is provided with an electromagnetic switch normally open switch which is connected with a jack. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. 1. If you are using industrial plugs, it is best to determine the total number of power sockets plugged into the equipment and the maximum power of the product itself. When the power output of the equipment plugged into your equipment exceeds the limit of the product, once the temperature exceeds the limit of the equipment itself, it will slowly overheat, and the limit of the shell and its components will lead to fire accidents, which will affect the safety of life. If the quality of the equipment is slightly worse, a large number of power plugs will be generated between each other, and spark discharge will be caused when starting the electrical equipment. 2. Be sure to insert the industrial plugs into all the industrial plugs in detail. When you are only half the difference, it will not only affect the socket when the equipment is in working attitude, but also the power plug and its electrical appliances. When the electrical appliances you use are still very large, it will easily cause spark discharge when the equipment is applied, which will lead to fire accidents. Figure 3. Industrial plugs should be used in places that children and teenagers cannot touch. Because most children and teenagers do not have relevant professional knowledge, it is easy to insert fingers or other objects into the plug and get electric shock. Some children will smash or throw away the industrial plug as a small toy, causing damage to the equipment, which may make the goods unusable or damage a certain part, resulting in abnormal impact of the electrical equipment used later. 4. The natural environment for the application of industrial plugs need not be selected. In the wet and cold natural environment, most customers should know that the influence of objects such as liquid or dust on their electrical equipment is absolutely great. Once they enter the equipment, they will cause fire accidents or short-circuit faults, so the natural environment you selected must not be wet and cold. It is better to select these dry and naturally ventilated natural environments to ensure the characteristics and quality of goods.
